Specification of Letters Patent.

Application filed April 6, 1912. Serial No. 688,871.

To all who met may Be it known that I, CHARLES K. SALis- BURY, a citizenof the United'States and resident of Milwaukee, in the county of Springs for CentrifugaLSeparator Bear ings, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This'invention relates to springs for the upper bearing of centrifugal separators, the spring being positioned between the hearing member and the frame to permit of oscillations or gyrations of the separator spindle in the bringing of the separator bowl to the proper speed. Various forms of spring means have been applied to this purpose and it is the object of the present in vention to provide one which will be inexpensive to manufacture and will be eflicient in use.

With the above and other objects in View the invention consists in the spring for separator bearings as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference inclicate the same parts in the different views: Figure 1 is a side elevation of a spring for a separator bearing constiiicted in accordance with this invention and shown as applied in use; Fig. 2' is a longitudinal sectional view thereof in place on the bearing sleeve; Fig. 3 is a transverse sectional View thereof; and, Fig. 4 is a plan view of the spring alone.

In these drawings 10 indicates a portion of the separator frame which is stationary and affords the opening containing the upper bearing for the spindle 11 of the separator' JO\Vl. This-bearing consists of a sleeve 12 containing a roller bearing 13 for the spindle 11 and provided withan upper frame as shown in Fig. 1. The lower ring portion 16 of the spring by engaging the lower flange 15 of the bearing sleeve keeps the spring in place. i

In operation the bowed spring straps 17 connecting the top and bottom ring members of the spring may yield upon the tendency of the separator bowl to swing in any direction, but their spring action returns the bearing member to its normal central position at the end of such swinging tendency of the separator bowl and thus the bearing is centered though being free to yield when the movements of the separator bowl require it to do so.

hat I claim as new and desire to secure by Letters Patent is:

1. A spring for separator bearings adapted for connection with a bearing sleeve having a top and bottom external flange, comprising a single strip of spring metal bent to form a split sleeve for surrounding the bearing sleeve and having parallel transverse slots formed therein terminating be fore reaching the edges of the strip to leave an unslotted marginal portion of the strip at its top and bottom for clasping with spring action around the hearing sleeve and the lower external unslotted marginal portion adapted to rest upon the lower flange of the bearing sleeve, said strip being bent or bowed to have the strips between the slots form a spherical spring.

2. A spring for separator bearings adapted for connection with a bearing sleeve, comprising a single strip of spring metal bent to form a split sleeve for surrounding the bearing sleeve and having approximately parallel transverse slots formed therein terminating before reaching the edges of the strip to leave an unslotted marginal portion of the strip at its top and bot- Patented Nov; 2, 1915.

tom for eiasping witl'l' spring action around the bearing sleeve; said strip being bent or bowed outwardly at its intermediate. portion so that the connecting strips between the slots connecting the unslotted marginal portion at both ends of the device form bowed springsfor engaging the stationary partof the separator bearing at their middle portion Wl1ich springs are yieldingly restrained from straightening by the marginal per-- tionsof the device. v r 3 spring for centrifugal separator Copies of this patent may be obtained for spindles coin jrisinga tubul arisl e'eve having i 1 .7 longitudinal slots extending from nearones edge of thelsleeve to near the otheredge thereof, the strips of inaterial between the slots being bowed outwardly. g

In testimony whereof, I afli'x my signa ture, in presence ofjtwowitnesses.
